Description
The Electro-Voice Variplex
signed specifically for use in ultra-high-fi-
delity cinema applications. The system is
®
THX approved* and offers Electro-Voice
patented technologies. The Variplex
a full three-way configuration that addresses
many performance issues not addressed in
other three-way designs. The Variplex
employs ElectroVoice's patented
tense- (VI) variable-intensity low distortion
horn system. This design offers two funda-
mental advantages. The variable horn throat
impedance provides uniform sound pressure
levels over the entire auditorium. Conven-
tional horn systems attempt to do the same
by aiming the center of the high-frequency/
mid-frequency horn toward the rear of the
room. This conventional approach wastes
fully one-half of the system energy and head-
room, and radiates that wasted energy onto
the ceiling and walls, thus producing reflec-
tions that further degrade overall intelligi-
bility and system clarity. The patented vari-
able- intensity approach, on the other hand,
compensates for the natural phenomenon of
sound reduction with distance and produces

tion to resolve system resonances (or ring-

perform the job they were originally intended
to perform, that being room equalization and
correction of the spectral characteristics
inherent in the tranducers themselves. Prior
designs have frequently attempted to "re-
solve" loudspeaker design issues with elec-
trical equalizers. RMD

Low Frequency Assembly Instructions
Refer to Figures l and 2 for the following
The Low Frequency Unit comes shipped as
two pieces (2-TL606MXL's).
1. Turn one of the low frequency units up-
side down and the other is right side up, ar-
range as illustrated in figure 1.
2. Remove the isolation gasket stips from the
low frequency accesory bag (shipped with
TM
the HPK-Variplex -XL. Attach the strips to
the up-side down speaker as shown in figure 1.
3. Remove the locking brace the low fre-
quency acessory bag and attach it to the back
of the unit right side up.
